High chair structure

ABSTRACT

A high chair structure is disclosed. In the disclosed high chair, an upper tray board is elastically fixed on a tray assembly of a seat part thereof. In addition, two fixing-belt receiving grooves are disposed on two sides of the seat part, and two cover boards are disposed on the openings of the fixing-belt receiving grooves to cover thereon. Moreover, the high chair further comprises a desk part that can be separated from the seat part, so that the desk part can be used as a desk alone.

BACKGROUND Field of Invention

The disclosure relates to a high chair structure. More particularly, the disclosure relates to a high chair for infants use.

Description of Related Art

High chairs are provided mainly for infants, so that the short infants can have exclusive seats at dining, and the infants can have the same height as adults with a high sense of participation during the dining process. At the same time, parents can conveniently feed the infants.

In the present, a high chair has a seat part, long legs disposed below the seat part, and a tray disposed in front of the seat part. For example, children high chairs disclosed in patent TW M370355U1, infant high chair having removable foot pedals disclosed in patent TW I417071 B, and assembling structure of high chair disclosed in patent TW M379385U1.

However, when the shape of the tray is to be changed or the tray's surface is defaced, the entire tray has to be disassembled to reassemble a new tray. Moreover, if the tray and the seat part are made as one piece, the entire seat part also has to be disassemble, and the replacement cost and resource wastes are thus increased.

Furthermore, in the children high chairs disclosed in patent TW M370355U1, the infants high chair having removable foot pedals disclosed in patent TW I417071 I, and the assembling structure of high chair disclosed in patent TW M379385U1, the disassembled seat part cannot be used in other situations, and thus the use thereof is limited and not in line with economic benefits.

Moreover, since the legs of the high chairs above are longer than the legs of normal chairs, the volume and the occupied space of the high chairs are large when the high chairs above are actually used. However, the high chairs can only be seated by infants. Therefore, after the high chairs are not used or the infants grow up, the storage of the high chairs are not convenient.

In view of the drawbacks of the high chairs above, the inventors research and develop the high chair of this invention.

DETAILED DESCRIPTION

To more completely and clearly illustrate the technical means and effects of this invention, the detailed descriptions are set forth below. Please refer to the disclosed figures and the reference numbers.

Please refer to FIGS. 1 and 2. In this disclosure, the high chair comprises a seat part 1 and a tray part 2.

The seat part 1 comprises a baseboard 11 and a peripheral wall 12 extended from the baseboard 11 to define a seating space 13.

The tray part 2 is set up between the two sides of the peripheral wall 12 of the seat part 1 and comprises a tray assembly 21 and an upper tray board 22. Two sides of the tray assembly 21 are locked on the peripheral wall 12 on two sides of the seat part 1. A trap area 211 is disposed on the upper surface of the trap assembly 21. At least two concave holes 212 are disposed on periphery of the trap area 211. The upper tray board 22 is correspondingly accommodated in the trap area 211 of the tray assembly 21. Elastic tenons 221 are disposed on the outer surface of the upper tray board 22 to correspond to the concave holes 212. When the upper tray board 22 is correspondingly disposed in the trap area 211 of the tray assembly 21, the tenons 221 can just inserted into the concave holes 212 to fix the upper tray board 22 on the tray assembly 21, as shown in FIG. 4.

In the tray assembly 21, a shallow arc groove 213 is disposed on the periphery of the trap area 211 to form a gap between the tray assembly 21 and the upper tray board 22 after both are combined. Therefore, the tray assembly 21 and the upper tray board 22 can be easily separated.

Please refer to FIGS. 3 and 4. The outer surface of the upper tray board 22 has notches 222 to correspond to the concave holes 212. An elastic segment 223 is across two sidewalls of the notches 222. The tenons 221 are disposed on the elastic segments 223. Since the elastic segment 223 is suspended in the air to have elasticity. Therefore, the tenons 221 disposed on the elastic segment 223 also has elasticity.

Please refer to FIG. 5. Two fixing-belt receiving grooves 14 are respectively disposed on two sides of the peripheral walls 12 of the seat part 1. The fixing-belt receiving grooves 14 are respectively combined with one ends of back belts 15 and seat belts 16. Two free ends of the back belts 15, which are far away from the fixing-belt receiving grooves 14, are buckled each other. Two free ends of the seat belts 16, which are far away from the fixing-belt receiving grooves 14, are also buckled with each other. Two insert slots 141 are disposed on the upper edges of the openings of the two fixing-belt receiving grooves 14, and bumps 142 are disposed on the lower edges of the openings of the fixing-belt receiving grooves 14. Cover boards 17 are disposed on the openings of the fixing-belt receiving grooves 14. An insert sheet 171 is disposed in the insert slot 141. Grooves 172 are disposed on the cover boards 17 to receive the bumps 142. The cover boards 17 are used to cover the fixing-belt receiving grooves 14. When the back belts 15 and the seat belts 16 are not used, the back belts 15 and the seat belts 16 can be placed in the fixing-belt receiving grooves 14 and covered by the cover boards 17.

When the seat part 1 is installed on a general chair 4, the seat part 1 is placed on a seating surface 41 of the chair 4. The free ends of the back belts 15 on two sides of the seat part 1 are placed on a seat back 42 of the chair 4 and buckled to each other. At the same time, the free ends of the seat belts 16 on two sides of the seat part 1 are placed below the searing surface 41 and buckled to each other. Therefore, the seat part 1 can be fixed on the seating surface 41, as shown in FIG. 6.

Breach 173 are formed on one side of the cover boards 17 away from the insert sheets 171 to form gaps between the cover boards 17 and the fixing-belt receiving groove 14, so that the cover boards 17 may be easily opened.

Moreover, the high chair further comprises a desk part 3, as shown in FIGS. 7-12. At least three socket parts 31 are equiangularly disposed on the periphery of the desk part 3. Intercalation holes 311 are disposed on the socket part 31. Linking rods 18 are disposed below and extended downward from the seat part 1 to respectively correspond to the socket part 31. Fasteners 19 are pivotally disposed on the bottoms of the linking rods 18. The fasteners 19 are inserted into the intercalation holes 311 to fix the seat part 1 on the desk part 3. Supporting legs 32 are disposed below the bottoms of the socket parts 31.

Please refer to FIGS. 9 and 10. The bottom of the linking rod 18 of the seat part 1 correspondingly disposed on the socket part 31 of the desk part 3, such that the fastener part 19 is inserted into the intercalation hole 311 of the socket part 31 to let the seat part 1 and desk part 3 can be stably assembled and positioned. The seat part 1 and the desk part 3 can be quickly assembled when an infant needs to be fed. The fasteners 19 can be operated at the same time to separate the fasteners 19 and the intercalation holes 311, as shown in FIGS. 11 and 12, so that the seat part 1 can be removed from the desk part 3 to meet the requirement of small desks and chairs in the infant's life to increase the economic value of the high chair.

Please refer to FIGS. 8 and 10-12. The middle parts of the fasteners 19 are pivotally assembled with the linking rods 18, so that the two ends of the fasteners 19 can be moved like a seesaw. The end of the fastener 19 toward the seat part 1 is a pressing end 191. The other end of the fastener 19 toward the desk part 3 has a hook 192. The hook 192 is extended along the body of the fastener 19 first and then tilt upward to form an inclined surface 193 on the bottom of the hook 192. Therefore, when the seat part 1 is placed on the desk part 3 and the linking rods 18 are inserted in the intercalation holes 311, if the seat part 1 is directly pressed down, the hook 192 can across the top edge of the intercalation holes 311 and hook the intercalation holes 311 to adopt a pivotally connecting structure through the fasteners 19 and the inclined surfaces 193 on the bottoms of the hooks 192. Accordingly, the seat part 1 can be conveniently hooked and fixed on the desk part 3.
